Abstract

Background: The DanGer Shock trial shifted AMICS management by showing improved outcomes with early pLVAD support, though concerns about its generalizability persist. We assessed outcomes in pLVAD-supported AMICS pts stratified as DanGer Shock-like or non-DanGer Shock-like, using pooled data. Methods: DanGer Shock-like and Non-DanGer Shock-like pts were identified from the National Cardiogenic Shock Initiative (NCT03677180) and RECOVER III (NCT04136392) observational, multicenter, single-arm studies of AMICS pts revascularized with Impella. DanGer Shock-like was defined by absence of: STEMI, out-of-hospital cardiac arrest, IABP prior to Impella, use of Impella RP, and Impella use >24h from shock onset. Mortality was assessed at discharge, 30 days, and 1 year. Results: Of 804 pts in the pooled database, 539 with complete data were analyzed; 298 (55.3%) met criteria for the DanGer Shock-like group. Patient demographics were similar between groups. Non-DanGer Shock-like pts more often presented in CSWG SCAI stage E (79.3% vs. 44.6%; p<0.0001), with higher baseline lactate, more shock at admission, and greater use of inotropes/vasopressors. Among STEMI pts, door to support time was longer in the non-DanGer Shock-like group. Survival at discharge, 30-day mortality, or 1-year mortality did not differ significantly. (Figure) [Formula presented] Conclusion: Despite greater illness severity and delayed support, non-DanGer Shock-like pts had similar outcomes compared to DanGer Shock-like pts. While encouraging, whether Impella improves outcomes in non-DanGer Shock-like pts remains speculative and warrants confirmation in a randomized trial.
